Tim Klahs, head of investor relations for New York-based SFX, said the company has not yet filed documents with the Justice Department on the deal and has had no indication that the acquisition will be delayed because of government scrutiny.

A Justice Department spokeswoman in Washington declined comment.

The proposed $105-million purchase was announced in August. Sources both inside and outside the two companies told The Times this week that the Justice Department was eyeing the deal because of antitrust concerns.

SFX has quickly become the country's top producer of live entertainment through a barrage of multimillion-dollar acquisitions.
